Hey, so first my iPhone 4 one day decided to lose cellular connectivity and would sit at 'searching' 24/7/ Multiple sim cards from different carriers were tested, to no success and the usual wipe and restore. $280NZD later, my iPhone arrived apparently being repaired. However, two weeks later, or today, my 'repaired' iPhone has lost signal once again. So as the title says, does a repaired iPhone have a warranty? The original purchase warranty has since expired, hence the $280 repair cost. Also I noted that my serial number from my old iPhone and the repaired one are both the same. Is that meant to be right? I will be ringing Apple first thing in the morning as well. But thought I would ask. I have lost a bit of confidence in Apple's support when I was dealing with my first repair. Thanks.
